Filed: 1984-06-19
Abstract: PURPOSE:To enable the ventilation of the space as well as the cooling/heating operation with one integrated type air conditioner by a method wherein a ventilating door is automatically opened and closed based upon the operating condition of the air conditioner and the temperatures of the room and outside. CONSTITUTION:During cooling operation, the ventilating door 10 is closed thereby performing cooling operation, because the indoor air being heated up to the temp. t3 and above by a heat exchanger 3 installed outside flows through an outdoor air passage 7, while shape memory alloys a12 and b13 are heated up to t3 and above, and the length of the shape memory alloy a12 is elongated to l2. At this time, when the outdoor temp. reaches between t1 and t2, the length of the shape memory alloy a12 comes to l1, thereby the ventilating door 10 opens with a support member 11 as a fulcrum, and ventilation is performed. In the warming operation to follow, the air being at temp. t1 and below being cooled by the outdoor heat exchanger 9 flows through the outdoor air passage 7, and both of the lengths of the shape memory alloys b13 and a12 reaches l2, because the strength of the alloy b13 getting to the length l2 is larger than that of the alloy a12 getting to the length l1, thereby closing the door 10.

Patent JP-H0424429-A (JP)
Title: Heater
Inventor: KAJITANI TOSHIMOTO
IPC: F24D7/00
Filed: 1990-05-17
Abstract: PURPOSE:To simplify a control mechanism for indoor equipment and embody sophisticated room temperature control at low cost by transmitting an OFF signal of said indoor equipment to outdoor equipment, and setting the outlet temperature of a heater at that time as a proportional control end temperature of a combustion means. CONSTITUTION:After reading in the outlet temperature THB of a heater when a room temperature, which turns off equipment, has reached T5, a burner 15 halts its combustion and a proportional control end temperature of the burner 15 T2 is substituted for T2'. At the same time, the outlet temperature T1 of the heater, which comes in proportional control from the maximum amount of combustion Hi of the burner 15 is substituted for T1'. The substitution lowers a proportional temperature zone in the early stage from a range of T1 to T2 to another range of T1' to T2' and forces the proportional control of the burner 15 to enter before room temperature setting takes place. Then, when the room temperature comes to return temperature T4, the burner 15 starts its combustion so that the amount of combustion of the burner 15 may be proportionally controlled so as to meet indoor heating load. Indoor equipment is designed to transmit an equipment on/off signal to outdoor equipment and shift the outlet temperature setting of the heater 13, thereby simplifying the control mechanism for the indoor equipment 23.

Filed: 1990-05-17
Abstract: PURPOSE:To prevent reduction off suction force of an open suction hole by providing a valve which is opened or closed according to difference of external or internal pressure in many suction holes on a hold face, and making suction force act on contact face only of an object when a workpiece is held on a table of machine tool. CONSTITUTION:Many suction holes 4 are formed on a hold face 3 of a hold tool 1 in which a vacuum chamber 2 is provided. A valve 6 is provided in the inside of a diameter expansion section 5 of each suction hole 4. When the suction hole 4 is sealed by an object 10, the amount of air which flows from clearance between the hold face 3 and object 10 is small. Accordingly, difference of external and internal pressure of the valve 6 is reduced, and the valve 6 is pushed outward by a coil spring 7. On the other hand, in the open condition where there is no object 10 in the upper section of the suction hole 4, the upper section of the valve 6 becomes atmospheric pressure, but vacuum pressure in a vacuum chamber 2 acts in the lower section of the valve 6. The valve 6 is suctioned toward an 0-ring 9 against a spring 7 as shown by chain line.

When the carriage 5 is impinged to the mechanical stopper of a starting point position, the motor M is forcibly stopped and MDRV is brought to L and an eddy current at this time is limited by a limiter 4. In the next step, MFWD is brought to H, MLIM to L and, succeedingly, MDRV to H and the carriage 5 is reversely moved by the reversal rotation of the motor M which is, in turn, stopped when a predetermined FBR signal is received and this position is set to the starting point.
